After years at the Palau de la Música Catalana, for the second year in a row L'Auditori hosts this always-awaited participatory concert, where dozens and dozens of singers perform Handel's 'Messiah', one of the composer's most popular works and a quintessential Christmastime piece. Josep Vila i Casañas is in charge of musical direction, and the vocal soloists are Irene Mas, Anna Alàs, Lluís Vilamajó and Elías Benito. Performing along with them are the Granollers Chamber Orchestra and the Amics de la Unió youth choir. Finally, the orchestra is Vespres d'Arnadí. It's a grand celebration for the performers and the audience as well.
